Emerson SLS1508 Product Details
Emerson SLS1508 Introduction
Emerson SLS1508 is a smart logic solver and an important part of Emerson DeltaV Safety Instrumented System(SIS).It is mainly used to perform safety instrumented functions(SIFs)to ensure the safe operation of industrial processes.
Main functions and features
Safety logic solver:SLS1508 is responsible for performing logic calculations in the safety instrumented system and making corresponding output decisions based on the state of the input signal to ensure the safety of the process.
I/O channels:Provides multiple types of I/O channels,including discrete input,discrete output,analog input(HART)and HART two-state output channels,which can flexibly connect various field devices.
SISNet communication:Communicate with other SLS1508 and SISNet repeaters through SISNet to achieve system-level safety functions.
High reliability:Redundant design and self-diagnosis function are adopted to ensure the reliability of the system.
Modular design:Modular design facilitates system expansion and maintenance.
Compliance with standards:Complies with relevant safety standards such as IEC 61508.
Application areas
SLS1508 is widely used in process safety systems in petrochemical,electric power,metallurgy and other industries to achieve the following functions:
High pressure protection:monitor process pressure to prevent overpressure accidents.
High temperature protection:monitor process temperature to prevent high temperature accidents.
Leak detection and alarm:detect process medium leakage and issue an alarm.
Emergency shutdown:quickly start the emergency shutdown procedure in the event of a dangerous situation.
